Oil Production in Indonesia’s Terang Gas Field Reaches 10 Million Barrels
The Japan Petroleum Exploration Co., Ltd. (JAPEX) and Mitsubishi Corporation (MC) are pleased toannounce that total production at the Terang gas field located in the Kangean PSC area in East Java,Indonesia has reached 10 million barrels of oil equivalent since the field started commercial
production on May 26, 2012.
The JAPEX-MC partnership in the Kangean PSC area goes back to May 2007, and since then, the 4oil and gas fields located there (Pagerungan gas field, Sepanjang oil field, PUO oil field and Teranggas field) have collectively produced oil and gas of over 20 million barrels of oil equivalent.
Representatives from Kangean Energy Indonesia Ltd. (KEI), the operator of the PSC area, Rudi
Rubiandini, Director of the Indonesian government’s Special Task Force for Upstream Oil and Gas
Business Activities (SKKMigas) and other relevant parties gathered in Jakarta on February 27 tocommemorate the achievement.
Terang gas field is located offshore, approximately 90km north of Bali (at a water depth of 90m) and ispart of the TSB gas field complex, which is composed of Terang, Sirasun and Batur gas fields. There
are 4 production wells, including horizontal wells. In the first 8 months of operations alone, production
from Terang gas field reached a total of 10 million barrels, with daily gas production averaging 240
million cubic feet (approximately 40 thousand barrels of oil equivalent per day). Natural gas producedin the same gas field is gathered in Floating Production Units (FPU) and transported through the EastJava Gas Pipeline to be sold to the state owned power company and fertilizer factories in the outskirtsof Surabaya, East Java. There is a strong demand for gas in the region, and the operation of thesegas fields will contribute to providing a stable supply of energy as well as to the growth of the local
economy.
As we move towards starting development on the Sirasun and Batur gas fields, also located within
the TSB field, we are simultaneously seeking to develop newly discovered gas fields such as theWest Kangean field, located offshore West Kangean Island, Indonesia and to start exploration at theSouth Saubi Prospect, where large-scale oil discovery is expected. Advancing in these efforts willcontinue to assist with ensuring a stable supply of energy to the Indonesian market.
